Webnoted that jointly exchangeable random measures, a notion to be de ned in Eq. (21), admit a representation theorem due toKallenberg(1990), providing a general construction for exchangeable random measures hence random graphs represented by such objects. This connection is further explored byVeitch and Roy(2015) WebThe property of exchangeability is closely related to the use of independent and identically distributed (i.i.d.) random variables in statistical models. A sequence of random variables that are i.i.d, conditional on some underlying distributional form, is exchangeable.

De Finetti's theorem, also called the de Finetti-Hewitt-Savage theorem, is a foundational result in probability and statistics. Roughly, it says that an infinite sequence of exchangeable random variables can always be written as a mixture of independent and … Web;A;P). A random measure W on a measurable space (S;S) is technically defined as a transition kernel from (;A) to (S;S). That is, a mapping W : S7! R + is a random …
WebA graphon is a symmetric measurable function . Usually a graphon is understood as defining an exchangeable random graph model according to the following scheme: Each vertex of the graph is assigned an independent random value Edge is independently included in the graph with probability .
WebThis paper builds on the framework of completely random measures (CRMs) and uses the theory associated with such processes to derive important network properties, such as an urn representation for network simulation, and relies on the Kallenberg representation theorem.
